# Checkout — Web app

The screen where users review their order and complete a purchase, one of the highest-stakes screens in any product with a transactional flow.

## Items

### Order summary
A clear breakdown of what the user is purchasing (item names, quantities, and prices)

_Tip: The order summary visible throughout checkout, since users shouldn't have to navigate back to check what they're buying_

### Total cost
The final amount the user will be charged, including any taxes, fees, or discounts applied

_Tip: Unexpected costs revealed at the last step are the leading cause of cart abandonment, so the total should be prominent and visible early_

### Payment method
Fields or options for entering payment details (card, PayPal, Apple Pay, or other available methods)

_Tip: Express checkout options like Apple Pay and Google Pay offered prominently, since they significantly increase conversion_

### Billing and shipping address
Fields for the user to enter or confirm their billing and delivery address

_Tip: Billing address defaulting to match shipping (with an option to uncheck if different) saves unnecessary typing_

### Promo code
A field to apply a discount code, positioned visibly within the order summary.

### Security indicators
Visual signals that the transaction is secure e.g. lock icons, SSL badges, or recognised payment logos

_Tip: Security indicators are suited to be near the payment fields_

### Confirmation step
A final review before the payment is submitted, giving users a chance to check before committing
